The blog post explores whether the names of lakes accurately reflect their physical properties, specifically color. The author analyzes a dataset of lake names and satellite imagery, using natural language processing to categorize names based on color terms (like "blue," "green," or "red") and image processing to determine the actual water color. Ultimately, the analysis reveals a statistically significant correlation: lakes with names suggesting a particular color are, on average, more likely to exhibit that color than lakes with unrelated names. This suggests a degree of folk wisdom embedded in place names, reflecting long-term observations of environmental features.
"A Colorful Game of Life" introduces a variant of Conway's Game of Life where cells have colors, inherited through a dominant/recessive gene-like system. Instead of simply living or dying based on neighbor counts, cells now also change color based on the colors of their neighbors, leading to complex and visually striking emergent patterns. The author implemented this colorful version using a custom-built cellular automata simulator optimized for performance using WebAssembly and shared the interactive simulation online. Users can experiment with different starting configurations and color palettes, observing the evolution of intricate, self-organizing designs and colorful ecosystems.
Hacker News users discuss the colorful implementation of Conway's Game of Life, praising its aesthetic appeal and clever use of color. Several commenters appreciate the smooth animations and the visual interest added by the color rules, finding it more engaging than traditional black and white versions. Some discuss the performance aspects, noting potential improvements and wondering about the implementation details. The creator's choice of using a pre-multiplied alpha blending technique is highlighted and its effectiveness debated. A few users express a desire for more configuration options, like adjustable speed and customizable color palettes. There's also a brief discussion comparing the web implementation to a desktop version and speculation about the use of WebGL.
Alfred Goldsborough Mayer's 1897 article explores the coloration of lepidopteran wings. He details meticulous experiments investigating pigment and structural colors, arguing that the latter, caused by physical wing structures like scales and ridges, produce iridescent and metallic hues. Mayer examines the influence of temperature and humidity on pupal development and resultant wing color, finding that these factors can significantly alter color patterns. He also delves into the protective value of coloration, noting mimicry and camouflage strategies, and theorizes about the physiological processes underlying pigment formation. Ultimately, Mayer connects color variations to environmental influences and adaptation, suggesting the importance of physical laws and evolutionary pressures in shaping lepidopteran wing coloration.
Hacker News users discussed the beautiful illustrations in the 1897 book, with some noting the incredible detail and artistry involved in creating them. Several commenters pointed out the historical significance of the work, mentioning the limitations of printing technology at the time and marveling at the quality achieved. There was also discussion about the scientific value of such meticulous documentation of natural patterns, with some wondering about the original purpose of the research and others highlighting the ongoing relevance of studying these patterns. One commenter even connected the aesthetic appeal of the patterns to their potential functionality in nature, such as camouflage.

Hacker News users discussed the methodology and potential biases in the original article's analysis of lake color and names. Several commenters pointed out the limitations of using Google Maps data, noting that the perceived color can be influenced by factors like time of day, cloud cover, and algae blooms. Others questioned the reliability of using lake names as a proxy for actual color, suggesting that names can be historical, metaphorical, or even misleading. Some users proposed alternative approaches, like using satellite imagery for color analysis and incorporating local knowledge for name interpretation. The discussion also touched upon the influence of language and cultural perceptions on color naming conventions, with some users offering examples of lakes whose names don't accurately reflect their visual appearance. Finally, a few commenters appreciated the article as a starting point for further investigation, acknowledging its limitations while finding the topic intriguing.
The Hacker News post "Do Lake Names Reflect Their Properties?" with the ID 43007453 has several comments discussing the linked article about lake color naming conventions. Many commenters engage with the premise of the article, which explores whether descriptive names like "Green Lake" or "Muddy Lake" actually correlate with the water's visual properties.
Several commenters offer anecdotal evidence supporting the article's findings. Some share personal experiences with lakes whose names accurately reflect their color, while others point out exceptions where the name is misleading or has evolved over time. For example, one commenter mentions a "Clear Lake" that is now murky due to pollution, demonstrating how environmental changes can impact the accuracy of a name.
A recurring theme in the comments is the historical and cultural context of lake names. Some suggest that names given by Indigenous peoples often reflect the lake's properties more accurately than names assigned later by settlers. Others discuss how the meaning of names can be lost or altered over generations, leading to discrepancies between a lake's name and its current appearance.
The discussion also touches upon the challenges of objectively measuring and classifying lake colors. Commenters acknowledge the influence of factors like lighting, depth, surrounding vegetation, and suspended particles on the perceived color of a lake. They point out that a "green" lake might appear blue on a sunny day or brown after a heavy rain, making precise categorization difficult.
Some commenters express skepticism about the article's methodology and conclusions. They question the sample size of lakes studied and the reliability of using historical records and online resources to determine color. Others suggest that the correlation between name and color might be coincidental rather than indicative of a deliberate naming convention.
Several commenters offer additional perspectives on the topic, such as the role of language in shaping perceptions of nature, the importance of local ecological knowledge in naming practices, and the potential for using remote sensing technology to accurately map and classify lake colors. One commenter even links to a related study on the naming of geographic features.
Overall, the comments on the Hacker News post provide a lively and multifaceted discussion of the relationship between lake names and their properties. They offer a blend of personal anecdotes, scientific insights, historical context, and healthy skepticism, demonstrating the diverse perspectives of the Hacker News community.
